In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ieee802154: cc2520: fix FIFOP work use-after-free<\/p>\n
The FIFOP interrupt handler queues cc2520_fifop_irqwork. On removal,
\ncc2520_remove() only flushes the work. The devm-managed FIFOP IRQ
\nremains active until after ->remove() returns and can queue the work
\nagain after that flush, allowing it to run after the private data is
\nreleased.<\/p>\n
Disable the work with disable_work_sync() instead of flushing it, so
\nthe handler can no longer queue it once removal begins. Destroy the
\nbuffer mutex last, since the worker and the stop callback invoked
\nthrough ieee802154_unregister_hw() both take it.<\/p>\n
